To all whom it may concern:

-Be it known that we, PA'lTRlCK J. CON- xous zlltl GEORGE Krrcn,citizens of the Unitet States, residing at Greenville, in the county ofMercer and State-of Pennsylvania, have invented certain new and usefulImprovemcnts in Valves or Cocks, of which the following is aspecification, reference dra wing.

Our present invention relates to an improved valve, and has specialreference to an air or steam cylinder cock, the valve bein soconstructed that the casing is prov1 ed with an upper and a lowerchamber, in which is slidably mounted a valve stem carrying two valves,one of which controls the admission of steam into the upper chamber,

while the other operated upon by either steam or air pressure to controlthe first mentioned valve.

To more clearly illustrate our invention attention is invited to theaccompanying drawings, in which Figure 1 is a side elevation of thecomplete valve or cook. Fig. 2 is a vertical cen- .tral section with thesteam inlet opened.

Fig. 3 is a similar view closed.

Referring to the drawings :The numeral 1 designates the main steam pipe,which is connected to the exteriorly threaded and reduced inlet 2, whichformsthe upper end of the casing 3. ,The casing is divided. by means ofthe internal ring or partition 4, into an upper chamber 5, and a lowerchainher 6, the lower chamber 6, being closed by means of the cap orcover 7. Formed in the upper end of the inlet 2, is a valve seat 8,while formed just'below the partition or ring 4, is another valve seat.Slidably mounted in the casing and extending from the inlet 2 into thechamber 6, is a valve stem 10, which carries upon its upper end theintegral valve 11, which normally upon the valve seat 8, thus preventingthe admission of steam into the chamber 5,while upon its lower end 12,is removably carried the large disk or piston 13. This piston 13 isadapted to be forced into engagement with the valve seat 9, when air orsteam to operate the same is admitted through the inlet port-14. Anoutlet port- 15 is provided in the upper chamber 5-, whereby when thevalve 13 is operated to unseat the valve 11, steam admitted. therebyinto the upper chamber is exhausted. The admission of the operatingfluid, either air or steam, into the chamber 6, is or may be controlledby means of a three-way cock, as may be desired. i

The spring 16 is mounted in the lower chamber and is adapted to be actedupon by the cap or cover 7, to exert a tension toward the closing of thepiston 13, thereby when there is no steam pressure upon the integralvalve 11, the spring normally holds the valve 11 unseated, and valve 13seated, or in other words when the engine stopped.

From the torc oiugdescription taken in connection with the drawings, theoperation of our air or steam cylinder valve or cock is clearlyunderstood, but briefly stated it is as followss-Vhen the engine, notshown, is started, the pressure ot'steam in the main steam pipe 1 seatsthe valve 11, compressing the spring 16 and opening the disk valve 13.Should it be desired to open the valve 11, air or steam is admitted intochamber 6, and as the valve 13 is of greater area than the valve 11, andthereby has a greater force exerted thereon, the stem is raised, and thevalve 11 unseated, thereby allowing steam to-enter the upper chamber 5,and exhaustthrough its outlet.

hat we claim, as new, is

' In combination with a pressure pipe, and an inlet pipe for operating acylinder cock, of a cook or valve, comprising a casing provided with anopen interiorly threaded lower end and a reduced extcriorly threadedinlet, said inlet being connected to the pressure pipe, and providedwith a valve seat upon its extreme end and within said pipe, a cap orplug for the lower and ot the casing, said casing being provided with acentral partition, which divides the easing into an upper compartmentwith an exhaust outlet and a lower con'ipartment communicating with theinlet pipe, a valve stem slidably mounted in the partition and in thereduced exterior threaded inlet, said stem carrying a valve upon itsupper end movable within the pressure pipe and adapted to be seateduponthe first mentioned valve seat, and also fur- D ther provided with aseries of grooves in the body of the stem adjacent to the rippercomartment of the inlet, whereby as the valve 18 unseated pressure isadmitted into the upper compartment and exhausted therefrom, a pistonslidably mounted in the lower c0111 artment of the casing and connectedto the In testimony whereof we afiix our signaihwer end of the "alvestem, the lowermost tnres in presence of two \vltnesses. point of saidiston beingobove the com PATRICK J.
